Yes there's definitely a few guys who give a good date, but dating mainly to do activities with people their own age (hobby groups can be full of older people and weird people).
Or build more attractive contacts on social media... If you've got a good Instagram network maybe he wants access?
It's hard to build a support network of attractive established mainstream people in a new city, dating is a way to fast-forward it.
I went on a first date with an eligible guy new to town, he was so polite, attentivs, paid etc. We went for a walk but no physicality.
He messaged a lot, suggested tennis for our next meet, he cancelled due to work.
I message suggesting seeing a play, and he said he wasn't interested. Then no suggestions (maybe he'd have been interested if I'd invited him to a party haha).
If he was really into you, you'd be his social priority. Not in a stalker way but he'd be interested in sealing the deal quickly (not sex, but you'd be priority over other social stuff).
If he's into you he'll know after a 10 hour date and having messaged/known of you for a month. He'll want the chance to speak his mind and impress you.
He won't need time to make up his mind. If another guy swoops in he'll be upset.
I think if I was you I would message just as I wouldn't want to be hanging around all weekend seeing if he came back about the show? I'd want to clarify and know my schedule.
But also not messaging and just waiting it out is an option.
If he's into you he won't be put off by whatever you ask. If you haven't messaged him in two days you're hardly overwhelming him!
It sounds like your intuition is saying he's drifted after initially pursuing you.
I wouldn't want to be on his list of "social networking options" if I wasn't after friendship. Or if friendship was fine with me I wouldn't prioritise him over dates.
